Retro Tech Restorations

Retro Tech Restorations

Hi! My name is Kristof. I restore & repair vintage electronics and other equipment as a hobby.
You can currently find restoration videos of tube and transistor radios and other types of vintage audio & test equipment on my channel. In the future I plan to expand the content to analog photography gear, arcade gaming and other thrift store finds. I hope you enjoy my videos. All feedback is greatly appreciated, but please keep things civil in the comment section.

Because I personally dislike mid-roll advertisements at lot, I limit these on my channel. I only put at maximum one mid-roll every 15-20 minutes. Videos which are shorter than 30 minutes are always mid-rolls free.

Should you wish to support the channel directly, you can always buy me a coffee (see link below).

    Congrats on finishing this repair! I did two Philips reel to reel machines last year, and they absolutely exhausted my patience for that brand, even though neither was as bad as yours. One tip for adjusting 4-track heads like on this recorder - use a stereo tape and put it in parallel mode, then adjust until it sounds right. It will be VERY noticeable when you hit the sweet spot. One other tip - put some oil on the felt clutch pads under the two reel tables. I know it seems counter intuitive, but it really helps with the smooth running of these mechanisms.

    Thanks for the tips. I used a commercially recorded stereo tape to align the head in parallel mode and that worked well indeed.

    Hoi Kristof, dank voor je mooie video's. Als vijfjarig jochie (in 1962) stond ik met open bek te staren naar de bandrecorder van mijn vader, waarschijnlijk de voorganger van dit model, ik herken de interne mechaniek duidelijk, het uiterlijk was net iets anders, maar soortgelijk. Als vierjarige had ik de afstemknop van de middengolf al verkend. Hilversum, Droitwich, Veronica en Waver, de Kleine Klaas wist ze te vinden. Maar nu kon je geluid ook nog opnemen en de Kleine Klaas was geflabbergaasd. Terwijl mijn moeder de huisarts belde om te vernemen hoe mijn onderkaak weer omhoog kon en mijn vader mij de werking van de machine verklaarde, nam de frustratie toe. Ik was immers vijf en mocht dus nergens aankomen. Maar op mijn zesde verjaardag kreeg ik een fantastisch cadeau! Een bandje om mee te oefenen! Het was een goedkoop rotbandje, in de eerste plaats omdat we rasechte ollanders waren, maar natuurlijk ook omdat mijn vader verwachtte dat ik het bandje zou verknoeien. Ik heb dat inderdaad gedaan, maar pas dertig of veertig jaar later. Ik werd beroeps en werkte met machines als de A80 en A820. Oh well! Wat betreft die wow en flutter... de "rondheid" van je aandukrol doet daar niets mee. De capstan moet een "toerental en rondheid" definieren, de aandrukrol drukt alleen maar aan. De kracht van aandrukking is waar het om gaat, die moet voldoende zijn. Verenstaal verliest veerkracht door de decennia, een nieuw veertje doet wonderen. Hoeft geen origineel veertje te zijn, experimenteer maar. Nogmaals: verenstaal verliest veerkracht door de decennia, het wordt slap. Nu ben ik gepensioneerd Kristof en ik geniet van je video's. Dankjewel! Klaas Kruik

    Hoi Klaas! Bedankt voor de leuke reactie. Ikzelf ben geboren in de jaren 80, dus ik heb helemaal geen voorgeschiedenis met bandopnemers. Bij mij waren het cassettes, maar het effect was hetzelfde. Voordat ik aan deze bandopnemer begon, had ik zelfs nog nooit met een bandopnemer gewerkt, laat staan eentje gerepareerd. Bedankt voor je complimenten over mijn kanaal. Blijf zeker kijken, zou ik zeggen, want ik heb nog meer dan 40 bandopnemers in stock dus er volgen er zeker nog!

    Hi Kristof, wow this really is a case of victory against the odds! That head / pressure pad adjustment was typical of Philips - I don't think they ever considered that someone would have to re-adjust it outside of the factory where they probably had special alignment tools / jigs to do the job easily. I note that you added your own blood -curdling curse to many I have uttered while working on Philips equipment. I once wished Phillips design engineers an eternity of sitting bare-bottomed on splintery wooden benches in a cold dark cellar, forever re-stringing the dial cords they designed ... And that belt residue! Anyway you have certainly won this one. It's a great little unit and works probably as well as it did when new. Loved the tape recorded intro by the way! Cheers

    Great work! Looks really nice now. Is the center of the pinch roller made of plastic as it looks to be? I see the replacements you can get (for about 28USD) have brass center. If it's plastic, one option could be to drill out the worn out part in the center and inserting a brass tube there.

    Its strange that it is hot chassis radio and it has phono input connected directly to chassis. In other radios there was always small insulation transformer for this input. Also ground and antenna were separated from chassis by "safety" capacitors of its time - something like 1n-5n/1kV.

    Hi Kristof Great to get a result like that after so much hard and dirty work! Are you still getting belt residue on your fingers? From my experience with my tape recorder years ago, I think the lack of treble on one track is probably azimuth adjustment of the head. My memory is that it was a fiddly adjustment but I'm sure you'll sort it out. Looking forward to the final video! Cheers

  • @retro_tech
    @retro_tech11 күн бұрын

    Yes! I'm still finding belt residue in some places. It's incredible how it gets everywhere. And indeed, it's probably a head alignment issue. Both height and azimuth, I guess. I'll have to align it by ear because I don't have alignment tapes. Thanks for the compliments! My capacitors arrived yesterday, so I should be able to continue the work next weekend.

    If you were looking for a R2R with simple mechanical construction, I think you got the wrong one 😅 For the next R2R I would suggest one from Tandberg, they are much simpler mechanically, but strong and well buildt. Go for the late 60s, early 70s models, if you can find one that actually needs fixing. There's many of them out there, but they just seemes to work forever. Impressive job so far anyway, dont give up, now starts the fun part where you discover that the heads are not working 😂

    Hi Kristof. This is quite a nice little retro piece. I wonder of the wow might be caused by the cassette itself. Is it the same on different cassettes? The spools can jam if they're wound too tight. I always used to give them a bit of a twist before putting them in, or run them through on fast forward & rewind. Cheers

  • @geirendre

    From the frequency of the wow&flutter i would suspect the pinchroller too. I usually take out the flywheel when i have it open like you had, to lubricate the axel. The motors also probably could do with an overhaul. Open, clean and relubrication.

    A friend of mine had that record player back in the 70s. Not the entire combination, but the stand alone thing. I was always impressed by the sound quality. It looks quite simple and cheap, but whatever components they used inside the plain plastic housing sure did the trick very well. Back then I had a very basic BSR record player, and his Philips easily outperformed it.

    Hi Kristof Well, it has turned out to be a stylish and apparently quite collectable little radio. That oscillation is a bit of a mystery but I'm sure you will work it out. I wonder if your shorting tuning capacitor is in fact bad earthing of the rotor vanes. maybe attach a clip lead to the rotor to chassis & see if it changes? Anyway, another great job!

    Oscillation can come from positive feedback (or lack of negative feedback) in the amplifier. So check the 1K resistor and the 1uF capacitor between the speaker and volume control. It could probably also be something wrong with the output tube, so it starts oscillating when it gets hot enough.
